About Goodenia blackiana Carolin
Goodenia blackiana is a prostrate to ascending perennial herb, usually reaching a height of 200 mm (7.9 in), with stems up to 200 mm (7.9 in) long. Most of its leaves grow at the base of the plant, and are egg-shaped to lance-shaped with the narrower end pointing toward the base. The leaves measure 20–60 mm (0.79–2.36 in) long and 5–15 mm (0.20–0.59 in) wide, and have cottony, woolly hairs on their lower surface. Its flowers are arranged in racemes up to 50 mm (2.0 in) long on a 30–50 mm (1.2–2.0 in) long peduncle, or grow singly in leaf axils. Each flower sits on a 30–50 mm (1.2–2.0 in) long pedicel, with linear bracteoles 5–12 mm (0.20–0.47 in) long at the base of the pedicel. The sepals are narrow oblong to egg-shaped, and 4–5 mm (0.16–0.20 in) long. The petals are yellow and 13–14 mm (0.51–0.55 in) long. The lower lobes of the corolla are 5–6 mm (0.20–0.24 in) long, with wings approximately 2 mm (0.079 in) wide. Flowering occurs mainly from September to January, and the fruit is a more or less cylindrical capsule about 10 mm (0.39 in) long. This goodenia species grows in mallee, woodland and grassland in scattered locations in western and northern Victoria, and south-eastern South Australia.
